Scented Begonias Revisited

            By Laura Crum

            I have to start this guest post on my husband’s begonia blog by admitting that I am no begonia expert. Yes, my maiden name was Brown and my family has been growing tuberous begonias for four generations. My first paying job was weeding flats of baby begonias in the greenhouse. But I never officially worked in the family business. I did marry the begonia breeder, however. So I have a certain degree of familiarity with tuberous begonias. Still, my greatest knowledge of them comes from my life as a gardener, and growing begonias at my home.

            I have another confession to make. Begonias are not my favorite plant. No, my heart goes to roses. Not the stiff, upright hybrid teas of florists shops and formal rose gardens. No. I love roses like this.

            And this.

            And this.

            Sorry begonia aficionados, but can your begonias do this?

            These roses, ramblers and climbers all, are not just beautiful and vigorous (I love vigor in a plant), but they are richly scented, such that when you walk up to the lovely display in the above photos, the scent hits you like a wave. This is what a plant ought to be.

I was fond of begonias, but not overfond, despite my long history with them. Just as I don’t care for overly hybridized looking roses, I did not care too much for the huge, heavy begonia blossoms, nodding uncertainly on the weak plants, needing staking and always looking quite unnatural. I also counted it as a fault that such a voluptuous looking flower had no scent. Imagine my delight when my new boyfriend introduced me to the scented begonias he had bred and was raising. I fell instantly in love—with both the plants and the man. Since then I have grown scented begonias on my porch every year, and can say for a fact that they are one of my favorite plants in the whole garden. (Roses are still number one.)

The reasons I love scented begonias are many, and not just limited to scent. I will be the first to admit that the scented begonias have a faint, and usually elusive scent. It doesn’t often hit you in a wave, like the roses. (Though it does have that effect when you walk through a field of scented begonias.) Once in awhile the half dozen plants on my porch will scent the air on a warm summer afternoon. But almost always, if I bend to smell a blossom, it smells sweet. However, the virtues of scented begonias are more than their fragrance.

Scented begonias remind me of the old-fashioned roses that I grow—the ramblers and climbers. These begonias have a more “species” look to them and a more natural form than the larger-flowered types. The scented begonias are overall quite vigorous, have a mildly cascading habit, and don’t need staking. All things to love in my book.

Those who prefer the huge flowers of the classic large upright begonias may find the form of the scented begonia flowers disappointing. Here is a photo to show the contrast. (By the way, these begonias are growing on my back porch, and I am no professional grower. The scented begonia shown is the first flower of a plant that has come back year after year with no special care. It is the same plant shown in the photo above (Sunrise) of my son smelling a begonia, so you can see that its flowers do become larger later in the season.)

As you can see, the scented begonia has smaller, more “natural” flowers. Though I can admire the large ruffled flower, I think the smaller flower has more grace. This is exactly how I feel about the difference between the large flowered hybrid tea roses and the smaller flowered (and more vigorous) ramblers and climbers. I vote for grace, vigor and scent every time. But for some gardeners, I guess, size is what matters (did I really say that?).

Breeding Scent in Tuberous Begonias

A Little History



Happiness is a scented begonia



"The Gift of perfume to a flower is a special grace like genius or like beauty, and never becomes common or cheap." John Burroughs

Breeding scent in tuberous begonias, and getting those begonias to market, has been both a real challenge and a real pleasure.

Some of the original species used in the development of the tuberous begonia had scent (B. cinnabarina ,B. baumannii,  B. foliosa var.miniata,  B.fimbristapula,  B.capensis and B. fimbristapula) . 

There have always been a very few tuberous begonias that showed a faint scent among the general population, and there were even a few that made it to the public. 

B. Baumannii is the most fragrant species and after being discovered in 1891 was crossed on tuberous hybrids immediatly.  B. "Tiges de fer odorants" was brought out in 1892 by the the breeder Limone.  Various scented begonias followed by the same breeder using this species and tuberous hybrids.

 Our company marketed a scented begonia in 1939 called “Fragrance” that was a cross selected from among 50,000 seedlings obtained by crossing B. baumannii and tuberous hybrids.

Leslie Woodriff, the famous breeder known for originating the “Star Gazer” lily, made many crosses in an effort to produce fragrant tuberous begonias in the 40s and 50s, with some success.  He crossed B. Baumannii with regular hanging basket begonias and something called “species #1041 from the University of California”.  Mr. Woodriff produced a single called “Orange Sweety”.  He also produced scented begonias he named “Patty’s Sweet” and “Yellow Sweety”.   "Yellow Sweety" has had a long life among begonia growers.



Zak and #77KL (Scentiment Sunrise)



Rather than going back to a species begonia to obtain scent we have worked within Begonia x Tuberhybridia. That is why the flowers of our scented begonias are still the fully double flowers that we have come to expect.  There was a mistaken impression among the early breeders that it was the pollen that caused the scent.

About 1986 our company was contacted by Howard Siebold who, for 50 years, bred tuberous begonias, for scent, as a hobby.  Since we had a similar interest, I  began working with Mr. Siebold and exchanged plant material with him.  Golden State Bulb Growers bought the patents on two of Mr. Siebold’s tuberous begonias, Golden Anniversary and Sweet Dian.   Mr. Siebold just wanted to see scent returned to the magnificent flowers of tuberous begonias.  He had been working with crosses made from B. Yellow Sweetie. 

I think Mr. Seibold really wanted the names of his begonias to enter the market place.  They meant something to him.  He was very disappointed to find that a salesman will change any name to another if he thinks it will sell better.  Mr. Seibold’s Golden Anniversary was sold by Jackson and Perkins as “Nectarine Rose”.

While Mr. Siebold was an enthusiastic hobbyist, he did not have the facilities that we, at Golden State Bulb Growers, have for plant breeding.  He only had a small outdoor growing area to evaluate his crosses.  We have agricultural fields.

Mr. Siebold would send me his most promising crosses which I would plant out for him along with our breeding material in the fields in Marina.  He would come down from Fort Bragg once or twice a year and go through the crosses.  The scent in those early crosses was so rare that we would spend hours on our hands and knees smelling for the slightest scent.  Any that he wanted would be staked with a flag of a certain color and I would send them up to him after harvest.  Any he didn’t want were mine! 

We worked together for some years, and I can say for my part, that I enjoyed our relationship.  Unfortunately, Mr. Siebold passed away many years ago. 

When he died he gave many of this begonia tubers to me, including some B. Yellow Sweety and B. Love Song, and the rest went to the Strybing Arboretum. 

He did have one annoying habit though.  He would send seed from one of his scented crosses to anyone who asked! 

Every time another begonia breeder comes up with a scented begonia, I remember those little seed packets going all over the world.

And doesn’t it just frost me every time some begonia salesman comes up with “the first scented tuberous begonia in the world”  The patents for Golden Anniversary and Sweet Dian were in the late 1980s, and “Fragrance” was found way back in 1939. And then there were Leslie Woodriff’s fragrant begonias and don't forget Lemoine's crosses in 1891.

Breeding for scent and finding the right plant within a field of flowers, is only half the battle.  Because the fragrance is so elusive, it is necessary to clone the plants.  Tissue culture of begonias, while relatively straight forward, is still tricky.  Things can go wrong at the last moment, just before planting out to the greenhouse. 

In the past, we have worked with several commercial  tissue culture labs with only limited success.  For example, we have ordered 30,000 clones only to be delivered 2,000 of which half would fail when removed from the tissue culture vessel!  This just drove our sales guys crazy.  A lot of our sales were through garden catalogs (remember garden catalogs?) and if the customer had printed his catalog, (at great expense) he would not be happy when we failed to supply, or supplied 300 when he ordered 5,000.  We have always been a wholesale operation, and having less than a thousand of anything sometimes slips off the radar. 

We have our own lab now but still have problems.  Some years we get lots of one sort, the next year lots of different sort the third year very little of anything. 

Some years we have one or two thousand, some years a couple of hundred, it’s frustrating.

I saw in a White Flower catalog once a Blackmore and Langdon scented begonia for $140 per tuber!

When something is rare, it is more valuable.

The fragrant begonia is an item that fits the retail / internet model of marketing better than the catalog/ wholesale model. On the internet we can sell what we have and that’s that. No upset middleman.

Golden State Bulb Growers hold 8 patents on scented begonias, two with Mr. Seibold as inventor and 6 with my name on them. Golden State Bulb Growers has trademarked the term Scentiment® for them.   The 4 newest patents are much improved over the 4 original (including Mr. Seibold’s 2 original).  There are fifteen more candidates for patenting being evaluated.

Scent is a funny thing.  Give different people a scented flower and they all smell something different. “Smells like honey” , “Smells like Fruitloops cereal”, “Smells like apricots” “Smells like Lemon Pledge!” all from the same plant!

The other thing with scent is that your nose soon looses the ability to discriminate the subtle differences in fragrance.  I have learned a trick from the perfume industry.  It is to take a few coffee beans and put them in a baby food jar and whenever my nose starts to burn out, I’d give the jar a shake and open it up, take a whiff, wipe the slate clean and start again.

The scent in begonias is not overwhelming.  It is not like jasmine, gardenia, or narcissus.  It is subtle.  The scent is produced by a volatile oil and it is most noticeable as the day warms up, at the end of a long hot day there is not much scent left.   In the greenhouse it is very noticeable, getting out of the truck among a field of them is quite heady.

One time Justin Brown and I were going through the scented begonias in the greenhouse, trying to decide if they were worth keeping or not.  We were going down the benches, plant to plant, smelling the flowers, passing the nice ones back and forth. “Um, this one’s nice, try it”.  At the time a greenhouse worker, a young man, was going along and watering dry pots.  When he got to us he remarked “Tough job, eh?”  Well, yes it might just look like the ideal job.  Smelling the flowers.

I don’t think they’ve ever made us a dime.
